Call Abort
The SD1+ can be programmed so that if it is
accidentally triggered, the call can be
aborted. Once aborted, the dialler will stop
dialling out immediately. The SD1+ can be
aborted by one of the following methods:
when a signal is applied to the abort input,
when the input that triggered the unit is
removed, or when the user passcode is
entered. When an abort is performed by the
code, the display shows " " as visual
confirmation of the abort being carried out (a
chime tone will also be heard). See page 6.
Last Call Log
The SD1+ has a last call log, this enables the
user to find out who the unit has dialled and
who acknowledged it. The log also shows
which input was triggered last. See page 7.
Acknowledgement Options
Once the SD1+ has made its call and
delivered its message, it requires a signal to say
that the message has been successfully
received. This is done by the recipient pressing
the number "8" button on their telephone. See
page 14. When the SD1+ has been
acknowledged, it will shut down until it is
triggered again. This option determines how
many times the unit must be acknowledged
before it shuts down. See page 7.
Telephone Numbers
The SD1+ can dial up to four different
telephone numbers. These numbers can be
up to 24 digits long and are programmed
using the LCD display and keypad on the unit.
The numbers can be forced to tone or pulse
dial if required and a pause can also be
programmed. It is also possible for the SD1+ to
dial a pager and send a numerical message,
this message is programmed by the user (a
digit is also sent after the message that
corresponds to the trigger input e.g. 1, 2,3 or 4
= Trigger A, B, C or D). See pages 8-11.
Recording Messages
The SD1+ has a built-in microphone so that
phrases can be recorded directly into the unit.
The message that is sent by the SD1+ consists of
a common phrase (0) which normally states
your name & address, followed by phrase A, B,
C or D which relate to the inputs applied from
the control panel (PA, burglary and fire in our
example). The SD1+ has up to 40 seconds of
recording time which has to be shared by all 4
phrases. It must be noted that if 10 seconds is
initially used by phrase 0 and you need to
re-record that phrase, 10 seconds must be
used by the new phrase 0. See page 12.
Deleting Phrases & Numbers
Because the SD1+ has a Non Volatile Memory
(NVM), the phone numbers and messages
cannot be deleted by removing power from the
unit. This option, allows you to delete all phrases
or all phone numbers as required. See page 13.
Playing Back Messages
Once the phrases have been recorded by the
SD1+, they can be played back through the on
board speaker so that you can check the
recorded message. It should be noted that
when you play back phrases A, B, C or D, phrase
0 is always played first. See page 14.
Sending a Test Call
Once the SD1+ has been programmed, each
message can be sent to a particular number to
test whether the unit is working correctly. When
the unit is in this test mode, everything on the
phone line will be heard through the speaker.
The display will also give a visual indication of
what is happening during the call. See page 15.
Three Way Calling
This is a service that is normally provided by
British Telecom, if this service is enabled, the
SD1+ will use it to prevent anyone trying to block
the telephone line. See page 16.
